|Comment||Synonymy: Iverson (1979) synonymized extant K. flavescens stejnegeri Hartweg 1938 with the Pliocene– Pleistocene fossil taxon, K. arizonense Gilmore 1923, based on similar morphology. Considered a subspecies, K. f. arizonense, by Iverson (1979b), it was subsequently recognized as a distinct species based on genetic analysis by Serb et al. (2001). Recently, McCord (2016) examined all available Pliocene material of K. arizonense and compared it with extant specimens, and concluded that the fossil material differs significantly from the extant material and is actually more similar morphologically to K. flavescens (sensu stricto). As a consequence, he restricted the name arizonense to the Pliocene fossils and resurrected the old name stejnegeri for the extant species. This conclusion was also tentatively accepted by Joyce and Bourque (2016), and we follow these recommendations here, accepting the resurrected name K. stejnegeri for the extant species previously known as K. arizonense (TTWG 2017).|
Subspecies: SERB et al. (2001) suggested to elevate K. f. arizonense and K. f. durangoense to full “phylogenetic” species status.
Synonymy: partly after RHODIN et al. 2010.
Habitat: freshwater (swamps, quiet rivers)
|Etymology||Named after Leonhard Hess Stejneger (1851-1943), Norwegian-born herpetologist who moved to the US in 1881 and became curator of reptiles at the Smithsonian Institution in 1889.|
